Here are some tips and suggestions for successfully completing Programming Project One, Recommend Treatment.
Do not wait until the last minute. This is not a particularly difficult assignment. However, it has a lot of moving parts.
Do a top-down analysis and divide your program into components. The classic input-process-output analysis is not a bad place to start. You might even consider isolating the calculation using the Smithfield formula as a function.
Use specific prompts. If you want the user’s weight in kilograms, ask them for their weight in kilograms. Be specific. If your calculations require the number of solar cycles, ask your user for the number of solar cycles. Be specific and explicit.
Get your program to work correctly without the required loop that allows your user to repeatedly estimate the Biximent Metabolic Index. Add the loop later. Use comment statements to identify what you want to do in the order you want to do those things.
For example, insert a comment that identifies the need to validate user input after each place in your program where you accept input from your user. Then, come back and add the code to validate all the user input values after the program works correctly.
Use your knowledge of the hierarchy of operations to evaluate the Smithfield formula correctly. Be careful.
Display the Biximent Metabolic Index (BMI) estimate using two decimal places. For example, display 124.65 instead of just 124.7. Validate your program’s output with some known parameters. Use the example output in the instructions. Come up with your own verifying cases. Test your program thoroughly before submitting it.
The planet Qwork is currently experiencing an outbreak of Ginjuk, a serious, contagious disease. Inhabitants of the planet Qwork are divided into three distinct genders, identified by the letters: “R”, “S”, and “T”. Each of the three different genders are affected in slightly different ways when they contract Ginjuk.
Your job as Medical Officer for the Interplanetary Aid Society (IAS) is to recommend treatment for inhabitants who may have contracted Ginjuk. Treatments vary from medication and ultraviolet light baths to hospitalization based on gender and several other factors. You must write a computer program that evaluates citizen responses from interview questions, determines the Biximent Metabolic Index (BMI), and recommends an appropriate treatment based on the value of BMI.
The Biximent Metabolic Index (BMI) value can be estimated very accurately by using the Smithfield formula:
BMI = (Weight BL GF) / Age
Where: BMI is the Biximent Metabolic Index (BMI), Weight = weight in kilograms, BL = Biximent Level, Age = age in solar cycles, GF = Gender Factor.
Gender factors for each gender type are as follows:
R or r: 0.77
S or s: 0.25
T or t: 0.53.
A comprehensive battery of tests has been administered to all citizens. They reliably determine the level of Biximent that is present in the circulatory system of each inhabitant. Weights are reported in kilograms and inhabitants report their age as a number of solar cycles.
Below is the table showing which treatment should be recommended based on the Biximent Metabolic Index (BMI) value.
Less than 75: Mild case, no treatment required
75 or greater, but less than 127.5: Serious case, medication treatment
127.5 or greater, but less than 280: Acute case, ultraviolet treatment
280 or greater, but less than 375: Severe case, replacement therapy
375 or greater: Extreme case, hospitalization.
It is important to note that if the Biximent Metabolic Index (BMI) value is greater than 195.00, inhabitants are considered “Highly Contagious” and an additional line of output is required in your recommendation report.
Your program should do the following:
1. Prompt the citizen for their weight in kilograms.
2. Prompt the citizen for their age in solar cycles.
3. Prompt the citizen for their gender identification (R, S, or T).
4. Prompt the citizen for their Biximent level.
5. Calculate the Biximent Metabolic Index (BMI).
6. Display the recommended treatment for that level of BMI in a nicely formatted comprehensive report that:
- Echoes the input parameters.
- Displays the Biximent Metabolic Index (BMI) level to 2 decimal places.
- Recommends treatment appropriate to the BMI level.
- Identifies a “Highly Contagious” condition, if appropriate.
Lower-case letters (r, s, and t) are sometimes used by the clans that inhabit the northern hemisphere of the planet to indicate their gender. These letters should be treated the same as their upper-case equivalents. Your program must guard against bad values by validating all input data. Numeric entries must be nonzero and positive but may be entered as floating-point values. For example, a citizen’s weight may be entered as 147.25 kilograms.
The number of solar cycles can also be reported using values such as 12.5. Biximent values are typically reported using a floating-point format. Remember your training and have confidence. Citizens of Earth are immune to Ginjuk. These people need your help!
Here are two examples of what your report for each citizen could look like:
For a citizen of gender type R, who is 20 cycles old and weighs 150 kilograms with a reported Biximent level of 30, the Biximent Metabolic Index is 109.58 and medication treatment is recommended.
Biximent Metabolic Index Report:
Gender: R
Age: 20 cycles
Weight: 150 kilograms
Biximent Level: 30
BMI: 109.58
Recommended treatment: Medication
Remember to add an additional line of output when the Biximent Metabolic Index (BMI) value for an inhabitant is greater than 195.00.
Biximent Metabolic Index Report:
Gender: S
Age: 20 cycles
Weight: 100 kilograms
Biximent Level: 31
BMI: 232.50
Recommended treatment: Ultraviolet
Inhabitant is Highly Contagious.
Your program should execute repeatedly allowing multiple citizens to be evaluated and have their treatment recommended.
To receive full credit for this programming assignment, you must:
- Use a correct file name, “XYProjectOne.java,” where “X” and “Y” are your first and last initials. For example, if your name was Edgar Polk, the file you submit should be named “EPProjectOne.java.”
- Submit a program that executes correctly.
- Interact effectively with the user in your prompts and error messages.
Paper For Above Instructions
The project involves developing a Java program to assess the health status of the inhabitants of planet Qwork, amidst a Ginjuk outbreak. This requires user interaction to collect vital statistics, such as weight, age, gender, and Biximent level. It's crucial to ensure that the program validates the input, particularly to avoid errors in BMI calculations, which depend on accurate user data.
The user will be prompted to input their weight in kilograms, age in solar cycles, gender (either R, S, or T), and their Biximent level. Specific prompts help guide users in providing the necessary information while ensuring clarity and specificity. For instance, asking “Please enter your weight in kilograms:” avoids confusion compared to a more vague prompt.
This program's central function is to calculate the Biximent Metabolic Index (BMI) using the Smithfield formula:
BMI = (Weight BL GF) / Age
Here, the Biximent Level (BL) and Gender Factor (GF) vary according to the gender identification of the user. The program defines Gender Factors as follows: R = 0.77, S = 0.25, and T = 0.53. This differentiation acknowledges the various ways genders respond to the Ginjuk disease, thereby tailoring medical recommendations.
Upon collecting the user's data, the program calculates the BMI and determines the appropriate treatment based on the BMI value. For example, a low BMI (less than 75) may not require any treatment, while higher values categorize treatment needs ranging from medication to hospitalization. Additionally, if the BMI exceeds 195.00, the program includes a warning, indicating the user is "Highly Contagious.”
The importance of accurate output display cannot be understated. Results will echo the user's inputs in a comprehensive report. For instance, if a user inputs values indicating a serious case, the program must display that information concisely while meeting formatting requirements, such as providing the BMI to two decimal places. A sample output could read:
Biximent Metabolic Index Report:
Gender: R
Age: 20 cycles
Weight: 150 kilograms
Biximent Level: 30
BMI: 109.58
Recommended Treatment: Medication
This approach combines clarity with the essential recommendations stemming from the BMI calculations, ensuring users understand the treatment options available to them.
Moreover, the program should allow for repeated evaluations, accommodating multiple citizens by repeatedly prompting for new entries until the user decides to exit. Such functionality enhances user experience and engagement, fostering a more interactive application.
Correct input validation is vital for this assignment. Users may enter unexpected values, thus creating a need for preemptive checks within the program logic. Any input needing evaluation should discern non-numeric or negative figures, ensuring the program only processes valid data. Suggestions for user errors must be articulated through clear error messages, prompting for corrections until valid input is provided.
In conclusion, the programming task involves crafting a sophisticated input-processing-output flow that processes citizen data while being user-friendly. This engagement with citizens of Qwork reflects a simulation of medical assistance tailored to their unique conditions during a crisis. An effective implementation not only adheres to the instructions provided but also prepares the foundation for future project enhancements, like integrating a graphical user interface or expanding the treatment options based on evolving data.
